TYPEWRITING MACHINE.

Application filed December This invention relates to stencil-card holding and typing devices for typewriting machines.

One of its features is the provision of improved means for automatically controlling the ribbon mechanism, so that it may be thrown in front of the types at certain times, but withdrawn while the type 1s striking the stencil-blank.

This device is particularly adapted for use in connection with stencil-cards for addressing machines which comprise a comparatively heavy paper or cardboard frame, htLV. ring on opening, across which is stretched a stencil-sheet. It is generally required to write the name or other identification mark at the top edge of the card, on the paper frame, and then the full name and address are typed on the stencil-sheet.

One of the features of this invention is the provision of means for handling said card with the mini-11mm effort, and consequently means is provided whereby the card may be easily inserted in a frame, whereon it is su'pported by Qpringdingers. The frame supporting the card is geared to the platen by means of a ,gearnndrack arrangement in such a way that when the platen is turned forwardly, the frame and the card thereon are lowered, and, when the platen is rotated rearwardly, the lines are spaced in the card similarly as if the card was fed around the platen in the ordinary Way. Having inserted the card in the frame, the platen is rotated by means of a lover or crank at one end of the platen-shaft and the frame is lowered to a stop which locates the position of a line of typing near the leading edge of the card. At this time it is required to type a line by means of the ribbon, and, for this purpose, mechanism is provided cooperating with the lower end of the frame for automatically elevating the ribbon to 5, 1924. Serial No. 754,055.

sink down to a position out of the range of the type, so that a line of type may be cut in to the stencil-blank. Successive lines of type may be cut into the stencil by line-spacing the platen in the regular way, and, for this purpose,- mechanism has been provided whereby the stop controllingthe position of the first line in the stencil-blank is released when the line-space l-ev-eris actuated;

Said mechanism comprises a pawl which, normally interposes a tooth in a disk fast on the platen-shaft, and, by means of a link operatively connected to the line-space lever, the pawl is withdrawn from in front of the tooth in said disk at every actuation of the line-space lever. 7 Other features and advantages will hereinafter appear.

Figure 10 is a diagrammatic View, inside elevation, showing the relative position of the ribbon-mechanism when lowered to clear the type when typing upon the stencil-blank. Referring more particularly to Figure l in the drawings, a Remington typewriting machine is illustrated into which there is built a stencil-device which forms the subject of this invention. Numeral 1O indicates the typewriter-frame, 11 is the carriage, 12 are the keys which are operatively connected to type-bars 13 by means of the links 14 and 15 actuating on a bell-crank 16. The type-bars 13 are pivoted at 17 and are swung thereon for striking the types 18 against a platen 19 which is revolubly mounted on the carriage 11.

A card 20 is inserted in a frame 21, between linger-springs 22, which hold the card in a position as shown in Figure 5. The frame 21 is operatively engaged with the platen by means of a gea '-and-rack arrangement comprising the racks 23 and the gears 24. Said gears 24 are fast on the platen 19 and are operatively connected to the frame 21 by means of the racks 23 which operate the latter when the platen is rotated. The frame 21 is slidably mounted on a fixed frame which comprises supporting members and cover-plates 26 fastened to the members by means of screws 27.

The frame 21 and the card 20 are then lowered to a position, against a stop 29, so that a. line of typing 30, near the leading edge of the card, may be typed thereon. In order to lower the frame 21, the platen is swung forwardly by means of a lever 31 fast on the platen-shaft 32.

It is desired to type the first line of type on the frame 33 of the card 20 by interposing a ribbon 34 between the card and the types 18. To this end, there is provided mechanism whereby the ribbon 34 may be elevated to its effective position as shown in Figure 1. Normally the ribbon 34 is held in its ineffective position as shown in Fig ure 8, clearing the type. lVhen the stencil-frame 21 is lowered, its lowermost edge 35 strikes av forwardly-extending arm 36 of a bell-crank 37 which is pivoted at 38 on a downwardly-exteiiding bracket 39, fast to the typewriter-frame 10. A downwardlyextending arm 40 of said bell-crank 37 engages an upwardly-extending arm 41 of another bell-crank 42 pivoted on a screw 43 fast to the bracket 39. Said bell-crank 42 is provided with a forwardly-extending arm 44, the end of which is operatively connected with a ribbon-lifting frame 45, the uppermost end of which carries the ribbon 34.

It will be apparentthat when the frame 21 is lowered and its lowermost end 35 stri res the arm 36 of the bell-crank 37, the ribbon 34 will be elevated to a position in front of the type, so that when the keys 12 are struck and the type-bars swing, the types 18 will make impressions on the card. A spring 46 is provided for the purpose of rendering ineffective the ribbon 34 when the pressure on the bell-crank 37 is released. Said spring 46 is fastened to the bell-crank 42 by means of a pin 47 and to the bracket 39 by means of a pin 48, and is normally under tension tending to lift the arm 36 of the bellcrank 37 and to lower the arm 44 of the bellcrank 42 upon which the ribbon-lifting frame is mounted. Said lifting frame is slidably mounted on a guiding member 96 fastened to the type-bar-segment 1O by means of screws 97. t will be noted that the lifting frame 45 is made of flat material and at the uppermost end a wire 98 is provided for supporting and lifting the ribbon 34.

Since one of the purposes of this inven tion is to facilitate the writing on a stencil having edge enclosing frames where it is de sired to ink type upon the frame, near the leading edge, and to out through the stencilblank with the bare type, it will be neces sary to withdraw the ribbon from in front of the type in order to cut the first line of typing 49 on the stencil-blank. This is done automatically by the spring 46 when the frame 21 is raised and the bell-crank 37 is therefore released.

In order to raise the frame 21 so as to bring the stencil-card in a position for cutting the first line of typing thereon, the lever 31 is swung rearwardly up to a position where a pawl 50, mounted on the carriage of the typewriter, interposes a tooth 51 cut in a disk 52 which is fast on the platen-shaft 32. This p6sition is designed to correspond with the position of the first line 011 the stencil-blank. The pawl is pivoted on a screw 53 fast on the type writer-carriage 11, and is held bearing against the disk 52 by means of a spring 54.

l/Vhen it is desired to cut more lines of typing on the stencil-blank, the distance between them should be uniform, and to this end, means are PIOXlClGCl whereby the linespacing lever 55 may be used and the card raised one space at a time for successive lines of typing. The lever 55 is swung on a bearing-and-shaft arrangement 56, and has at the rearmost end a crank 57 fast to the lever by means of a screw 58. Said crank 57 is operatively connected to a bell-crank 59 by means of a link 60, in such a manner that when the lever 55 is swung, the link 60 is moved downwardly, and, by rocking the bell-crank 59 on a pivot 61, a link 62, operatively connected to the bell-crank 59 by means of a pin 63, is forced rearwardly to thus throw a pawl 64 into engagement with a ratchet 65 fast on the shaft 32. The pawl 64 is pivoted at 66 upon a lever 67 which is fulcrumed on the platen-shaft 32, so that when the link 62 is moved rearwardly, due to its being connected to the pawl 64 it will first throw the pawl into engagement with the ratchet and then will feed the same in lll) line-space direction up to the point where a rearwardly-ertencling heel" 69 stri'li es a roller 70, which is resiliently mountedonaispring 71 and actsas a retainer forthe ratchet-65.

In order that the pfaten ma be fed, it is necessary first to withdraw thepawl 59 from in front of the tooth 51 in the dish 52. To this end, there is l royidedemechanism Where by the t portion of the travel of the lever 55 is utilized to witl idi aw said" pawl and which may comprise a rearward'ly-extending link 72 operatively con-necti'irgthe pawl at 73 and the hell-crank 59 74-, so that as the bell-crank is swung forwardly the fink 72 will push on and rock the pawl away from the dish 52-, thereby clearing the tooth There is provided a plate7 5 having the upper end 76 'bent for taking the upward thrust of the pawl- 50 when strticlbhy the tooth 51 on the disk 52, said plate being firs tened to the carriage-frame hy' m'eans of a screw 77 It will be noted that the lever returned to norma'l posi tioir by the spring The Remington typewritinpgr machine is normally operated inl ower case position and is usually provided with mechanism for elevatiii-g the platen to upper-case; Said n'rechanism in'clndes a platen-frame 79 sup ported by linlis 80 which are pivoted at 8-1 on the carriage and serve to support the frame 79' and'to move thesame in astraight up and down line; Since this mechanism is not necessary in this typeof a device in which" it is desired to type all characters lower case", there are provided screws 82' to loci; the platen in lower-case position, and thus prevent its accidental sl'ii fting" to upper case. The steneil devic'e is mounted li ie'tween side frames 25, secured on a shaft by means of screws 83, and is spaced between two collars 85, which positionthe same. A tie rod 86 unites the members 25 so ast-o keep the several associatedpa ris together when the device is withdrawn from the machine. Said shaft 86 is'iiastened' tothe members 25 by means of fasteners which are shown in the drawings in the fermof'screirs 87 and nuts 87;

It is customary to provide a backing for the types in the form of a ceilil n'loid coveri-i'rg 88 around the pl aten, and, d ne to the fact that it is exposed tothetype-blows, it is desired to mount it onthe-platen in a" manner which. will renderit easily removable: To this end, there are providedtwo clamps 89 and 90 fastened to the platen by means of screws respectively numbered 91 and 92. Said clamps are made of resilient material and are so designed that the heads of the screws holding them are sunk into the platen in order that the card 20 may not interfere with the head of the screws when the platen is rotated to operate the card-frame.

A special scale 93 in the front of the machine has been provi ded',- substituting the" reg-al ascale, and the stops 94, normally adyustahle, have been fixed by means of screws 95 in order that the travel'of the carriage may he limited within the range of the card;

'It will he noted that the platen 19 is made comparatively smaller than the regularplaten, as in many casesit he re uired to use the machine with doable-shift case, and it has been a found-- in Plt-IC'EICG that a platen of small ClittIllStQlfaQd-HKZGS consider ably the possihili' ty of double-printing.
